Dear Linux kernel developers and maintainers:
We are writing to report a kernel bug discovered with our modified
version of syzkaller.
The bug was initially found in Linux kernel v5.15.189 (commit
c79648372d02944bf4a54d87e3901db05d0ac82e). We have attached the
.config file and symbolized crash report for your reference.
Unfortunately, we do not have a reliable reproducer at this time. We
are actively analyzing the root cause and working to create a
consistent reproducer, which we will share as soon as it is available.
Please let us know if you need any further information.
Best regards,
Jiaming Zhang

This is likely to be a false positive. We found the default kernel
timeouts are not really suitable for fuzzing. Consider using the
official syzkaller-recommended configs with proper tuning for fuzzing.
Additionally, v5.15 is extremely old. Check out:
